公路超高渐变方式探讨

Gradual Approach of Superelevation of Highway

公路超高设计是公路几何设计中十分重要的方面,合理的超高设计是保证曲线路段行驶车辆的横向稳定和行车舒适安全的主要措施。在介绍近年来公路设计中常用的几种超高渐变方式的基础上,结合对公路路线设计规范相关条文的理解,分析了各种方式的利弊,以期为实际工作提供参考。

Superelevation design is a very important aspect in geometric design of highway. Reasonable superelevation design is the main measure to guarantee the lateral stability, driving comfort and safety of vehicle at curve sections. Based on the introduction of several commonly used gradual approach of superelevation in design of highway in recent years, combined with the understanding on the related codes in highway route design, the paper analyzes the advantages and disadvantages of various methods, in order to provide reference for the practical work.
